    ci: Use F31 for new gnome-desktop3 API
    
    gnome-desktop3 has added new API that we need in gnome-settings-daemon.
    This API is not yet in an unstable release though, which means that we
    can safely build against F31 while building against rawhide will not
    work as of now.
    
    Switch to F31, this should not cause any further issues.
